BRUSH-MAKING MACHINE.

Specification of Letters Patent.

Application filed February 26,1906. serial No. 30%965.

reference being had to the accompanying drawings, which form a part of this specific-avtion.

This invention relates to brush-making machines, and has for its ObJGCt an improved machine in WhIOll the exact quantity of bristles which it is. desired shall. constitute each tuft in the brush is automatically gathered from a receptacle inwhich these bristles are stored in a mass and carried to the base of the machine, there to be engaged by a staple that has been contemporaneously and auto matically made from a strand of wire.

, From this oint the staple straddling the tuft of brist es is driveninto the brush-back and the tuft thus secured thereto.

The device of this application is in the natureof an improvement over that disclosed and claimed in my copending application, Serial No. 284,788,. filed October 28, 1905, title, Brush-making machines, the improvements lying in the direction of'simplicity and compactness of working parts, and consequently reorganization of some of the details of the mechanism. Like the device hereinabove referred to, this machine operates automatically, except as regards the placing of the brush-back in proper position to have the staple driven into it. 4

The machine is-fuliy illustrated in thesecompanying drawings, in which- Figure v1 is a perspective of the entire machine. Fig. 2. is a front elevation, partly in section, ofthe-woikmg parts of the machine,

Fig. 11 is an 'elevation of the le'itdiand side of the'icam wheel I-I shown in Fig. 1 Fig. 12 isan elevation of the driver and its regulating" feed-rollehiogether with the slide-bar which carries and actuates it. Fig. 13 is a view of the slide bar whose reciprocation actuates the picker or bristle-carrier. Fig. 14 is an elevation of the front, of the machine with the covering-plate removed, showing the relative position of the vertically-reciprocatin trackway' whereby actuation is imparted y'rneans of the pin 9 with the carrier, whose position is shown in dotted lines.- Fig. 15 is a view siinilarlyin elevation of a part of the same elements illus- 3 tratedin Fig. 14, showing'the relative osition of the parts whenith e rotation o' "the cam-wheel has IIIO'VGCI the reciprocatin slide to its lowermost point of travel and with the pin 9 at the opposite end of the horizontal trackway from that shown in Fig. 14.

A indicates the supporting or base portion of the device, from which rises an overhanging arm B, which carries most of the working parts of the mechanism. The topmost por-' tion of this arm B is formed to constitute a bearing J for the horizontal shaft S, from which all of the working partsreceive their actuation and to one 3 end of which is connected the driving-wheel 12, which is actu ated by the belt 12. This driving wheel is thrown into and out of operative connection with the shaft S by means of the clutch. C, which is pivoted at 5 to a porti'onof the arm B and which is actuated bymeans of the link L by pressure upon the treadle T. hen the operator releases thepressure of his fbot fromv the treadle, the rise of theflink'm'e'iiiber L, and consequently the disengagement of the clutch mechanism,is brought, about by the upward pull of the spring 1. Above the central portion of the machiiie'on the shaft S are mounted two cam members G and H, each face of each of which is provided with suitable ca m tracks or races, whose contour and relative position with respect to 'one another has been made a matter. of careful previous ad ustment. Into each of these cam-races PIOJGCtS an antifriction-roller, as

signed to actuate.

the engagement of ts antifriction-roller in the cam-race. From the lower end of the slide 40 projects a bracket 41*, in which is pivoted a pawl 41, which on each downward stroke of the slide engages with its lowermost point the teeth of a cog-wheel 44, which is fixed to one face of the wire-advancing wheel 45, which in turn is pivoted to one end of the lever 46. The lever 46. moves around its pivot-pin 4, which extends into the body ortion of the machine and has its horizonta portion (that'carrying the Wheel kept ressed firmly downward by the pressure o the spring 4 against the upper end of its vertical portion, the spring .4 being regulated as to its pressure by a nut which rests against the fixed lug 47. The periphery of the wheel 45 is serrated so as to frictionally engage the wire 18, which is uncoilecl from the s 001 19 and passes between its periphery an the pivoted rollers 48" and 48* on its way to the staple-forming mechan-- ism, the pressure of the spring 4 making the engagement of the periphery of the wheel 45 against the wire a very positive one. The diameter of the wheel is made a matter-of very careful 'revious calculation, the diameter chosen eing regulated by the size of wire used in order that at each throw of the wheel caused by the engagement of the pawl 41 against the cog-wheel 44 the exact length. of wire desired may be advanced. The greater the size of the wheel 45 the greater is the length of each advancement of wire, since the arc through-which the wheel turns at each stroke is the same. The return of the pawl 41 to a osition of alinement, as near as may be, with the slide 40 after ach stroke against the cog-wheel is provided for by the spring 39. (Shown in ig. 5.)

After passing the wheel 45 and the rollers 48 and 48 the wire passes on beyond the edge of the block 49 and into the track, wherein the staple-former reciprocates. This staple-former is actuated similarly to the slide 40 by engagement of its antifrictionroller 61 in the cam-race g of the wheel, G.

As it descends it engages theexposed length of wire, shears it off from the rest of the length by engagement of its cutting-face former 61 during the portion of each cycle of its movements. Its rear endl is connected by means of a bolt with theslotted end of one arm 65 of the bell-crank lever 65, which is held in place by the screw or' bolt 64, which extends vertically therethrough and through a lug p on the rear of the machine. The other arm 66 of'this bell-crank lever has its- 'free end shaped to engag'e'in the oblique slot 42,- which is in the rear face of the block 43 and which is fixed to the lower end of the slide 40, whose downward movement causes the arm 66, engaging, as it does, in the vertical slot 42, to be moved to the left, thus causing the part 67 a of the anvil to be projected into the path of the staple-former 60, as hereinbefore described. Similarly the upper or retractile movement ofthis slide 40 causes the arm 66 to move toward the left, thus causing the retractile movement of the anvil 67 after its function (the formation of the staple over the part 67?) has been accomplished. The positioning of the cam-races on the two faces'of the wheel G determines the exact timing desired on these two parts.

Engaging in the cam-race e in the lefthand face of the cam H, looking at the machine as it appears in Fig. 1, is the antifriction-roller 57 a of the slide-bar 57, whose vertical reciprocation, controlled by the rotation -of the cam-wheel H, actuates the picker or carrier member 29, which is mounted onpin m, which projects from the facing-plate13, and from the inner face of the slide-plate 21 of which projects apin 9, which engages in the horizontal trackwa 56, formed b the lower portion of this slide-bar 57, as s own particularly in Figs. 2 and 13, and because of the pivoting of the carrier 20 at m can as it to move back and forth in the trackway 56 and about the pin m as a center, its entire range of movement being somewhat less than ninety degrees. The peripheral edge of this carrier 20 engages against the forward and exposed face of a store of bristles 35 contained in the feed-box F, which is suitably supported by a portion of the overhanging arm B. The store of bristles is constantly pushed forward by the follower 36, which is under pressure of the weighted cord 37,

which engages over the rollers 37 on the side piece 32 of the feed-box. The stock of bristles may be replenished any time by raising the cover 34, which is pivoted to the side parts 32 and forcing back the follower as far as is necessary to furnish the. space required for" the extra bristles.

As shown in Figs. 7 and 9, the carrier'or picker 29 consists, essentially, of three parts, the central body portion 20, the slide-plate 21, and the supplemental piece 22. This last piece 22, which is held to the outer face of the bodyportion 20 of the carrier by bolts 22, of course moves at all times with the carrler and serves to keep-smooth and in ahnementthe bristles remaimng 1n the feedtween the central portion (wl-lich is engaged third of the way between the toe portion by the periphery of the carrier itself) and the ends of the bristles.

- On the reverse face of the carrier from that occupied by the supplemental piece 22 is a slide-plate 21, which 1s held to the body por ti'on of the carrier by bolts, which, though fixed with respect to the body portion, permit a sliding movement of the plate 21 with respect to the carrier within the limits permitted by the slots 7 and 8, through which they engage, the large flattened heads of the bolts reaching past the edges of the slots and engagin against the outer face of the plate 21 to hdld it against the body of the carrier. In Figs. 7 and 8 it will be noted that the slot 7 is of trefoil shape in order to impart to the plate and the carrier as a whole irregular motion (which will be hereinafter referred to) when the tuft of bristles is deposited adjacent to the newly-formed staple. The forward end 28 of the slide-plate 21 is formed to provide the terminal notch 28, which when the carrier is at the lowest extremity of its movement forms one side of the lower portion of the. staple-guide, and one leg of the newly-formed staple passes along and is guided by this notch in its downward movement. On the upstroke of each movement atuft-of bristles of the size desired'is gathered by the notch 27, which is located about 1:)-

'20 and the heel portion 20 of the part 20 of the carrier. The size of thisnotch for the purpose of determining the amount of bristles to e taken at each movement of mechanism is regulated by the piece 27, which is held in position by a bolt 27*. At the commencement of the downward motion of the carrier the first movement is of the slide-plate '21,

because of the engagement of the pin 9 in the raceway 56. This causes the slide-plate 21 to move forward before the body portion of the carrier is actuated and causes its forward end 28 to slideacross and close the notch 27. \Vhen the slide 21 has moved so far as the limits of the slots 7 and 8 permit, its motion is then imparted to the body portion 20 of the carrier, which in turn movesforward until the lower limit of its movement is reached. Similarly, the initial portion of the upward movement of the part 57 is communicated first to the slide-plate 21, causing the notch 27 to be opened again. Just at this eriod V the knife-carrying slide 50 is depressed y the engagement of its antifrict' ion-roller 51 in the cam-race k on the reverse face of the camwheel H. The roller 52, carried on its face, engages first against the inclined projection on the upper end 23 of the carrier '29. Passing from thence it next engages forcibly against the projection 26, both of which jolts cause the bristles to be shaken out of the new driver may notch and free to ,be moved downward, to gether with the staple, which has meantime been moved Kand which now straddles the tuft. The relative position and angle of the two projections 23 and 24 on the head of the carrier is regulated by these-rows 12 1 and :24",

- which engage through the top of the part 24,

whose inner end 'is pivoted to the portion 23 V at 23*. The exact timing of the impact between the roller 52 and the projections 25 and 26 is thus regulated. This jolting ofthe carrier and sliding of the plate 21 with respect to the body portion 20 causes the body portion 20 to drop downward with respect to the plate 21, resulting in the forward end 28 of the plate 21 being pushed upward and out of engagement over the notch 27, thus effecting the release of the bristles. I in one ortion of the left-hand face of the cam-wheeil H is a yielding'portion h, pivoted so that -the portion of its peripl'rery WlIlCil faces toward the center and toward the sha t- S is normally continuous with the fixed portion of the periphery of the cam-race c. .[t is yieldingly held in this position by the spring d, thus allowing for an irregularity in .the movement of the antifriction-roller, which engages in the cam-race during a portion of each rotation and correspondingly affecting the oscillation of the carrier.

On. the lower portion of. the driver-carrying slide is an eccentric wheel 53, part of whose'periphery is toothed and the remainder'is regularly circular. Against its lowermost portion the upper end of the driver 54 engages. In case t 1e extreme lower portion of the staple-driver 5-1 is broken off, as is frequently the case, the substitution of a be avoided by moving the eccentric piece 53 around so that a hi not the higl1est, portion of its peripherythat is, the port-ionfarthest from the pivot 53, which holds it in place-engages against the end, thus forcing it down so much farther.

The bruslibacks are supported on the table 14, which is immediately below the deto is.,regulated by the supporting-screw 15,

and its angularity with respect to the tuft inserting mechanism, whether perpendicular 'or otherwise, is determined by the arm 16,

which is pivoted to its lower face and is regulated as to its height by the thumb-screw 16! v 12'0 1.
